It has been brought to our attention that sometimes we write about people you don't know who do things you don't understand for reasons no one can explain. Normally, we'd just point you to Google and send you on your way, but we're not sure we can trust you to do your own homework. (You didn't do it in college, so why would you start now?) In light of that, we're now publishing DealBreaker Trading Cards™. We're starting with the basic, obvious people and working our way up (or down, as it were) to the more obscure, not-terribly important people who still make way more money than your average obscure, not-terribly important people. This week: our White Collar Criminals Series. First up: Ken Lay.
